Multifunctional polymethylsilsesquioxane (PMSQ) surfaces prepared by electrospinning at the sol-gel transition: Superhydrophobicity, excellent solvent resistance, thermal stability and enhanced sound absorption property

► Superhydrophobic PMSQ surfaces were prepared by electrospinning at sol-gel transition. ► Superhydrophobic PMSQ surfaces show excellent resistance to solvents. ► Superhydrophobic PMSQ surfaces show thermal stability as high as 300 °C. ► Superior acoustical performance was obtained when the sponge decorated with PMSQ.
